That is a really cool idea!
My best game and why... For me this is Ragnarök Online. On the european servers several years ago. I really loved this game. The graphics, the sound and the PvP system with the War of Emperium were a great experience. But what made this game so great for me were the acquaintances I have made in this time. With some of them I am still chummy. Those people were sticking to me in bad times and around in the good ones, for sure. That is why Ragnarök Online is my best experience. World of Warcraft and other games were great too. But this is the best.
That sounds amazing, I have made so many wonderful friends through my history of MMO's especially wow. I have been playing wow since Vanilla and the friends I have met have been amazing. It is so beautiful how games can bring people together. And help others through hard times.
